How to enable Notability Auto-backup to Google Drive
Ginger Labs and the D-E Computer Service department strongly recommends that everyone who uses Notability enables the Auto-Backup feature even if you already have the iCloud sync enabled. (Ginger Labs states that the iCloud sync is not intended as a backup.) Here is how to enable auto-backup to Google Drive:
In Notability, go to Settings.
Tap Auto-backup then Google Drive.
If you are not already signed in to Google Drive, you will be prompted to login using your d-e.org Google login (firstname.lastname@example.org) and My DE password.
Tap Accept to allow Notability to use your Google account.
Tap OK to the message that confirms you are all setup.
Back on the Settings screen under Google Drive Settings, change the File Format to PDF (instead of Note).
With Auto-backup enabled this way, PDF copies of all your notes will be saved in your Google Drive account under a folder called Notability. In addition to not losing your notes if something really bad happens to your iPad, you can access a view-only copy of your notes from any Internet connected computer (or even a smart phone) by logging into drive.google.com.
How to check your version of Notability
In Notability, go to Settings then tap About.
The version number is listed at the top of the screen.
What to do if Notability won't write or highlight using your finger
This can happen if you have used a a Logi Crayon or Apple Pencil with Notability. If you connect a Crayon or Pencil to Notability, it will only allow writing input with the Crayone/Pencil until you disconnect it.
To disconnect the Crayon or Pencil: Tap and hold on either the highlighter or pencil tools in Notability, then click Disconnect Apple Pencil below the settings for line thickness/color.
